STAVE-JOINTING llIACI-IINE.

To all whom it may concern:

Be it known that I, O. M. YOUNG, of Sinclairsville, in the county ofChautauqua and State of New York, have invented a new and ImprovedMachine for J ointing Staves; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specification, in whichFigure l is a side elevation of my invention a portion of the framingbeing taken away; Fig. 2 a transverse vertical section of the same takenin the line as, :0, Figs. 1 and 3; Fig. 3 a plan or top view of thesame; Fig. 4 a detached plan view of a portion of the same; Fig. 5 adetached edge view of the outer part of one of the levers M.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to obtain a machine by which staves maybe jointed with a greater or less bilge according to their widthor, inother words, have their edges cut with a greater or less degree of tapereach way from their center outward according to the bilge required, thelatter being determined by the width of the stave, the wider the stavethe greater the taper and vice-versa.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a framing which may be constructed in any proper way tosupport the working parts of the machine.

B, is a driving shaft at one end of the framing, and O, is a wheel atone end of the driving shaft, said wheel being provided with a radialslot 42, in which an adjust-able wrist pin D, is fitted, see Fig. 1.

E, is a rod one end of which is connected to the wrist pin D, and theother end attached to a slide F, which is fitted on a suitable guide G,attached to the framing as shown in Figs. 1 and 3.

H, is a curved rod or bar one end of which is fitted to the slide F, bya screw or pivot Z), the opposite end of said rod or bar being connectedby a pivot 0, to a rod L, which has two curved arms J, J, attached toit.

To the outer end of each arm J, there is a planer K, secured by a pivot(Z. These planers have their cutters e, placed relatively in oppositepositions as shown in Fig. 3, and each planer is fitted on a guide L,the inner ends of which are connected by a joint f. The outer ends ofthe guides L, are slotted longitudinally, and in said slots pins 9, arefitted, said pins being attached to levers M, M, the outer ends of whichare secured to the framing by fulcrum pins h. The pins 9, are adjustablebeing secured by nuts g, in oblong slots in levers M. The inner ends ofthe levers M, M, are connected by arms or links 2', z, to a slide N,which is placed in a guide O, on the framing and is allowed to slidefreely back and forth therein. To the slide N, a spring gage P, isattached the use of which will be presently described.

Q, is a frame which is composed of two uprights j, j, the lower ends ofwhich are secured to arms 70, 70, at right angles, the arms is, beingpivoted to the framing A, at V. Between the upper parts of the uprights7', 7', there is secured a bed piece R, on which the staves to beoperated upon are placed and secured by a clamp-bar S, the ends of whichare slotted longitudinally and fitted on the upper ends of the uprightsj, j. To the clamp-bar S, a spring T, is attached, said spring having atendency to keep the clamp-bar in an elevated state. The clampbar S, isslotted longitudinally and two projections U, U, are attached to theclamp bar by screws m, m, which pass through its slots. To each end ofthe clamp bar S, there is attached a rod n, and these rods pass downthrough the bed piece R, and are connected by chains V, V, to a shaft W,which is fitted between the lower ends of the uprights j, j, and has atreadle frame X, attached to it. The operation is as follows: The staveto be jointed is placed on the bed piece R, and secured thereon bydepressing the treadle frame X, with the foot, the projections U,bearing on the stave. The operator then shoves forward the slide N,until the gage spring P, strikes the edge of the stave. This movement ofthe slides N, actuates the levers M, and the latter through the mediumof the pins adjusts the slides L, L, so that the latter will have a moreor less oblique position relatively with each other. The shaft B, isrotated by any convenient power and a reciprocating movement is giventhe planers K, K, from the wheel C, by means of the rod F, the planersas the frame Q, is

shoved forward jointing the stave with a greater or less degree of taperaccording to the obliquity of the guides L, the latter being regulatedby the width of the stave itself in adjusting the gage spring P, to it.Thus it will be seen that each stave will be jointed with a taper inproportion to its width so that each stave whether wide or narrow willhave its proper bilge.

Staves of different lengths may be ointed by varying the length of thestroke of the planers which is done by adjusting the wrist pin D, in itsslot a, and a greater or less adjusting movement of the guides L, L,relatively with that of the levers M, may be
